These fun lightweight, bright colored cases slide apart to create a battery storage system. The BATUCA system and wells separate the batteries from contact and allow you to carry your spent (dead) batteries on one side, (live) batteries on the other side.

Did you know that FAA rules no longer allow loose batteries on a plane? Spare batteries must be protected from damage and short-circuiting. Batteries in checked baggage must be protected the same from accidental activation!
